1in the spring of 945, Dong Cunrui joined the local Anti-Japanese Self-Defense Forces and the Eighth Route Army in July of the same year. 1946 In early April, in the encounter of Dushikou, an important town in northern Chabei, he tactfully won an enemy machine gun and was awarded the Medal of Courage.
1At the beginning of 947, Chang 'anling was attacked by snipers. When the squad leader died and the vice squad leader was seriously injured, he stepped forward as the squad leader, completed the sniper task as scheduled, and made great contributions again. Before his death, he made three meritorious deeds and four minor acts, and won three medals for bravery and one medal for Mao Zedong.
1March, 947, during the training and consolidation in Pingbei, Dong Cunrui joined the Party. After Mao Zedong put forward the call of "overthrowing Chiang Kai-shek and liberating all China", troops from various strategic locations went to urban warfare in succession.
At that time, the PLA had no planes and lacked tanks, and mainly relied on limited artillery and infantry to carry out blasting. The class led by Dong Cunrui was praised as "Dong Cunrui Training Model Class" by the division and regiment leaders, and he himself was also awarded the title of "Model Blaster".
■ Before the Battle of Longhua started, Dong Cunrui, who won the "Marshal of Blasting" in the contest, expressed his determination on behalf of everyone: "Even if it turns into soil after death, I will fill it in the outer ditch of Longhua Middle School."
At the beginning of May, 1948, Dong Cunrui's army took part in the Battle of Rezecha. Longhua county is the treasury of Chengde, the capital of Jehol. The enemy built a large number of bunkers here in advance, and some specially built bunkers were also called "model fortifications".
On May 25th, 1948, the battle against Longhua County started. Dong Cunrui's 6th Company is responsible for clearing the enemy's core position-Longhua Middle School. Before leaving, Dong Cunrui, who was the leader of the blasting team and won the "Marshal of Blasting" in the contest, expressed his determination on behalf of everyone: "Even if I turn into dirt after my death, I will fill it in the outer ditch of Longhua Middle School, so that everyone can step on us and ruin Longhua!" He led his comrades to blow up the enemy's three turrets and five bunkers in succession. After opening the peripheral fortifications in the northeast corner of Longhua Middle School, the machine guns of the bridge bunker hidden by the enemy on the main river outside the wall suddenly opened fire, causing serious casualties to the troops, and the assault was blocked, while the comrades sent to blast fell one by one.
In the face of heavy artillery fire from the enemy bunker, Dong Cunrui well-documented again and rushed to the bottom of the bridge under the cover of his comrades. At this time, his left leg was interrupted by enemy machine guns, and the bottom of the bunker was a little high from the dry river bed. The berms on both sides of the river were steep and slippery, and the explosives he buried slipped twice because there was no wooden support. At this point, the charge signal has sounded. If you delay for another minute, more comrades will die. Dong Cunrui resolutely supported himself with his body, holding up the explosive charge with his left hand and lighting the fuse with his right hand. With a loud noise, the enemy's bridge bunker was blown up and the red flag was inserted into Longhua Middle School. Dong Cunrui opened the way for the victory of the troops with his young life and sacrificed his years.
